Summary

This remix have been modified and resized so it can be mounted on the CR-10 z-rod to keep it clean. Cut a dishwashing sponge, put some lubricant on it and mount it below the extruder motor. Use a piece of filament to lock it in place.

Make sure it does not get in the way when you home your machine!!

A tip is to use a simple g-code that runs the gantry up and down automatically a few times.
